The SV215 zoom eyepiece uses a simultaneous focus design. No matter how much you change the focal length, you don't need to refocus. (However, minor adjustments may be required.) The SV215 zoom eyepiece is mainly suitable for medium to high-end short-focus non-refracting telescopes and is mainly used for high-magnification observations of the Moon or planets.
In the process of zooming from 3 mm to 8 mm, the SV215 zoom eyepiece shows a constant field of view of 56 degrees, and invariably provides users with a completely different experience when using the zoom eyepiece. At the same time, the injection pupil distance remains 10mm.
Regarding magnification adjustment, the SV215 continuous zoom eyepiece uses a click-stop design. You can quickly change to an accurate preset magnification with a click that stops at 3, 4, 5, 6, 7, or 8 mm.
The SV215 zoom eyepiece has a lens configuration of 6 elements and 4 groups. Full multi-layer coating provides excellent transparency, contrast, and color correction.
The SV215 zoom eyepiece is equipped with a foldable, removable environmental protection rubber eye mask and an anti-slip rubber protective ring. Includes a safety undercut that fits securely into the eyepiece holder. The interface supports the installation of a standard 1.25-inch filter.
